GENERAL HISTOLOGY

Detailed explanation-1: -The mandibular branches of the trigeminal nerves help you bite, chew and swallow. In some cases, people develop numbness or other signs of trigeminal neuropathy from an accident, dental procedure or facial surgery. Trigeminal neuralgia can cause stabbing, shock-like facial pain or a constant burning sensation.

Detailed explanation-2: -The main symptom of trigeminal neuralgia is sudden attacks of severe, sharp, shooting facial pain that last from a few seconds to about 2 minutes. The pain is often described as excruciating, like an electric shock. The attacks can be so severe that you’re unable to do anything while they’re happening.

Detailed explanation-3: -Classical trigeminal neuralgia is caused by pressure on the trigeminal nerve close to where it enters the brain stem. The brain stem is the lowest part of the brain that merges with the spinal cord. In most cases the pressure is caused by an artery or vein squashing (compressing) the trigeminal nerve.
